i just watched a kai greene workout and he did a bunch of weird things then went up to 315 in the back squat with ridiculous ease of course
i am willing to bet kai greene could squat 300kg
Ya I know what you mean actually, we are seeing more of this these day.
the ones i know can do 5 plates, but its not perfect form, but i guess if its good enough to use 3, it is.
their legs speak for themselves anyway

this guy is a pro, in my gym, this is 5 and half plates
http://www.youtube.com/watch?v=nv-vChp6LFYi have to say, the form is good enough
wow, great set there, that's a 700+ pound squater for a single if suited up for sure
I never go past 4 plates ever, but I do my squats ass to the floor or at least as low as I can physically possibly go.
